davinci: da850: add support for SATA interface

Add support for SATA controller on the
DA850/OMAP-L138/AM18x devices.

The patch adds the necessary clocks, platform
resources and a routine to initialize the SATA
controller.

The PHY configuration in this patch is
courtesy the work done by Zegeye Alemu,
Swaminathan and Mansoor Ahamed from TI.

While testing this patch, enable port multiplier
support iff you are actually using one. The
reasons of this behaviour are discussed
here: http://patchwork.ozlabs.org/patch/78163/

ChangeLog:
v3:
Removed fields which were being initialized
to zero in PHY configuration. Moved SATA base
address definition to the top of the file to
make it inline with what is done for the rest
of the modules.
v2:
Addressed comments from Sergei. Removed unnecessary
braces and removed unnecessary else after goto.

davinci: Add additional JTAG code for AM-1808 and OMAP-L138 Rev 2.0 SoCs

From: Sudhakar Rajashekhara <sudhakar.raj@ti.com>

The JTAG variant code for Rev-2.0 silicon of the OMAP-L138 has changed.
In addition, the variant code for the AM-1808 SoC appears to match
the Rev-2.0 code for the OMAP-L138. Add an additional entry to support
these chips.

This patch is originally from a patch on the arago project, here:
http://arago-project.org/git/projects/?p=linux-omapl1.git;a=commit;h=6157618435e313a444cdf059702bd34036a6e2b7

http://linux.davincidsp.com/pipermail/davinci-linux-open-source/2010-November/021224.html

This patch was tested using an AM-1808 SoC on a MityARM-1808 SoM card. It
was also tested using a Rev 1.0 silicon OMAP-L138 on a MityDSP-L138F card.

davinci: am18x/da850/omap-l138: add support for higher speed grades

AM18x/DA850/OMAP-L138 SoCs have variants that can operate
at a maximum of 456 MHz at 1.3V operating point. Also the
1.2V operating point has a variant that can support a maximum
of 375 MHz.

This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz)
to the list of DA850 OPPs.

Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).

Because of this, we depend on the maximum speed grade information
to be provided to us in some board specific way. The board informs
the maximum speed grade information by setting the da850_max_speed
variable.

For each DA850 OPP, the normal ('NOM') voltage defined in the tecnical

is supported at.

The minimum ('MIN') voltage defined in TRM is meant to take care of
voltage fluctuations and the device should not be run at this voltage
for extended periods of time.

defined in the datasheet.

davinci: cpufreq: bailout on regulator errors

Current cpufreq code does not consider errors that can occur while
changing voltage. Code to increase CPU frequency goes ahead even in
the case the regulator has failed to increase the voltage. This leads
to hard error since lower voltages cannot support increased frequency.

Prevent this by not increasing frequency in case increasing voltage
is not successful.

Also, do not lower the voltage if changing the cpu frequency has failed
for some reason.

Note that we do not return error on failure to decrease voltage as
that is not a hard error.

Apart from one instance of genuinie repetition, most are are instances

removed the multiple definitions from the irq.h file in the hope
that someone might decide to use them as shared interrupts at some
point of time. The priority initialization however needs to be done

Davinci: iotable based ioremap() interception

This patch allows for a more flexible ioremap() interception based on iotable
contents.

With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized. Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.
